A forward auction is a marketplace where multiple buyers can bid against each other to obtain an item for sale from a single supplier. This can be done in person or electronically over the internet.  Sellers and buyers can be individuals, organizations, etc. Items are commonly placed at a special site for auction (e.g. eBay.com). Buyers can continuously bid for the items they are interested in. Eventually, the highest bidder wins the item. Two types of forward auctions are common. The first is a liquidate auction where buyers seek to obtain the lowest price for an item they are interested in. The second type is a marketing efficiency auction where buyers wish to obtain a unique item.
